On both sides, there is a push button. When the door closes, the roller pins are moved upwards into the strike plate located in the door frame through a push button movement, locking the door in place. This pulls the door leaf against the door frame. The eccentric roller pins allow for easy adjustment if needed. When the key is turned in the opening direction, the main bolt is retracted. A downward push button movement then moves the roller pins to the opening position. Subsequently, the latch is retracted.
